Log every dataLayer.push to the console
Wraps the dataLayer.push method to print, with a label, every event object pushed to GTM in the console.
Code to copy
try {
window.dataLayer = window.dataLayer || [];
var dl = window.dataLayer;
if (!dl.__jzLogged) {
var origPush = dl.push.bind(dl);
dl.push = function () {
try {
for (var i = 0; i < arguments.length; i++) {
console.log('%c[dataLayer push]', 'color:#F9AB00;font-weight:700', arguments[i]);
}
} catch (e) {}
return origPush.apply(dl, arguments);
};
dl.__jzLogged = true;
console.log('dataLayer.push logging enabled.');
}
} catch (e) {
console.warn('dataLayer logger failed:', e);
